Tungsten carbide roll ring has characteristics of good wear resistance, high temperature red hardness, thermal fatigue resistance and thermal conductivity and high strength, it is a key component of high-speed wire rod rolling. Tungsten carbide roll ring is mainly used for high-speed wire rod mill pre-finishing unit, and finishing units, reducing sizing unit, rolling play area and improve the performance of rolling material effect decreases. Tungsten carbide roll ring line production to meet the needs of making various types of high carbon steel, alloy steel and special steel. Tungsten carbide roll ring material is developed on the basis of the tungsten carbide tool material, it is made of refractory metal compound (WC) as a matrix, and transition metals (Co, Fe, Ni) as the binder phase. Tungsten carbide roll ring has good abrasion resistance, high-temperature red hardness, thermal conductivity and high temperature strength and other characteristics, it has been widely used in making high-speed wire rod, bar, rebar, and other rolling seamless steel pipe production. During normal use, the surface due to the impact of high frequency alternating thermal shock and hot water fog and thermal fatigue cracking, commonly known as crack, different forms of wear or fracture failure is the main reason in this case appears thermal fatigue crack initiation and propagation. When the groove face cracked it must be grinded to prevent crack propagation caused by abnormal breakage roller ring. Tungsten carbide roll rings performance requirements When the roller ring used, the roll diameter roller ring is smallest , and line the fastest, roll ring subjected to thermal shock highest frequency. Therefore, it requires roll ring material having excellent abrasion resistance to ensure the dimensions of finished wire after a certain amount of rolling ; and requires a high fracture toughness to resist the thermal expansion of the higher frequency shocks caused thermal fatigue cracks; the same time, need to have a high thermal conductivity to suppress thermal fatigue crack initiation. During use, the maximum operating speed of tungsten carbide roll rings up to 18000 r / min, and rolling up to the maximum temperature of the contact 1200 ¡æ. It is in this harsh working conditions, the roller ring wear resistance, toughness, resistance to thermal fatigue performance high demands. To achieve these performance requirements, often using coarse-grained low cobalt grades roller ring, such as WC-6% Co. Tungsten carbide roll ring characteristics 1. Contains a microscopic hard spots, have a high resistance to abrasion 2. The macro-hardness is high, up to 69 ~ 81HRC or more. 3. Material hardening tendency serious. 4. Material with low thermal conductivity. 5. High intensity of the material. 6. Stable chemical properties, very high melting point. Tungsten carbide roll ring using requirements Heap of steel rolling process is inevitable accident, the heap of steel rolling various causes overheating will cause the roller ring side, while at the other side of the water-cooled quenching effect, causing the roll surface heat cracks, restoring rolling when this heat leaving the roller ring rapid crack propagation easily cracked. Because rolling at high speed rolling finishing train, the temperature is high, when the stack of steel metal deposited on the roller ring groove around, due to the effect of high temperature molten metal ring attached to the roller surface, forming a "product turtle" phenomenon. In this case, local heating roller ring, resulting in heat stress, heat fatigue easily formed, if the roller ring continued use, the potential cause fracture failure. Remove the stack of steel roll ring, regardless of the groove is available, should be re-grinding, in order to eliminate the stress roll ring to prevent thermal fatigue crack initiation and propagation. Tungsten carbide roller ring has good heat conduction properties, down less hardness at high temperature, good thermal fatigue resistance, wear resistance, high strength, and other characteristics,so it is suitable for high speed rolling, and it become the good choice for roller ring.

The composite roll is that cemented carbide roll rings and steel shaft are compounded into a whole through the special method, which is used for rolling round steel, screw steel, flat steel and angle steel, etc. We can supply various specifications of composite roll with |¦Ì300-500mm and 30-150mm of thickness. Our company possesses powerful R&D experience on cemented carbide roll ring. We develop a new pre-stressed composite roll independently. The roll has these characteristics: excellent structure, advanced manufacturing technology, is safe and reliable during use, big feed quantity of single groove, small quantity of grinding. It resolves the large-diameter roll ring application problems successfully. Advantages of composite roll The quality of steel products can be promoted. The surface quality and tolerance of products can be thoroughly improved. The negative deviation can be controlled more precisely. The change frequency of groove and roll can be reduced. The downtime can be shorted. The labor intensity can be reduced in rolling workshop. Increasing productivity and output can create greater economic benefit at the same time. The rejection rate of products can be reduced. Greatly reducing the steel cost for per ton is effectively way for enterprise to reduce cost and increase benefits.

Tungsten carbide roller has characteristics of good wear resistance, high temperature red hardness, thermal fatigue resistance and thermal conductivity and high strength , have been widely used in high-speed wire rod, bar, rebar, seamless steel tubes, etc. Domestic production of tungsten carbide roller materials mostly WC- Co, WC- Co- Ni- Cr two series, and the content of Co, Co- Ni - Cr is in the range of 6wt% ~ 30wt%. From the use of perspective, tungsten carbide rollers has good mechanical properties, its flexural strength up to 2200 MPa or more, shock toughness up (4 ~ ;¡§¡é 10^6 J/ m^2, Rockwell hardness (HRA) is up to 78 to 90, widely in the high-speed wire rod rolling process, which is much higher than single-slot chilled cast steel or high speed steel rolls. Tungsten carbide is made of tungsten carbide powder and binder phase (such as drilling, nickel, etc.), and then pressing and sintering, regardless of the conditions under cold rolled or hot rolled has excellent wear resistance, tungsten carbide rollers has been widely used in pre-finishing mill and finishing of high-speed wire rod currently. On the performance of tungsten carbide roller in hot-rolling wire rod , the material must meet the following requirements: 1. Sufficient anti-fracture strength; 2. Good abrasion resistance; 3. The smooth surface finish; 4. Excellent corrosion resistance, thermal fatigue, thermal cracking performance. Tungsten carbide roller rings can working in bad conditions , small profile rolling (especially rebar rolling) process conditions is harsher than the high-speed wire rod, and therefore corresponds to the profile rolling ,tungsten carbide rollers recommend using high binder phase carbide. Tungsten carbide roller material design Pre-finishing all vehicles roller should ensure its high toughness, strength, rigidity and thermal conductivity, followed before considering its wear resistance. When designing each vehicles roller, pre-finishing materials should choose carbide grades of Co, Co- Ni- Cr binder content is high (greater than or equal to 25wt%) , requiring an average WC grain size of coarse (5|¡§¬m ~ 6|¡§¬m), to obtain a higher shock toughness, proper strength and hardness. For the finishing of the roller movements, particularly the last two rollers of the finish rolling, which suffered load is small, and high relative velocity of the material to be pressed (80 m / min ~ 120 m / min). In this case, the wear resistance of the roller to be the most important requirements, and must ensure the strength , timpact toughness and hardness of a reasonable match, so the binder of Co / Ni content ratio and the average grain WC control of particle size and other factors must have greater control in front of different pre-finishing rolling roll. Tungsten carbide roller category According to the structure of tungsten carbide rollers, it can be divided into solid tungsten carbide roller and composite tungsten carbide roller. Solid tungsten carbide rollers have been widely used in pre-finishing and finishing stands high speed wire rod mill (including fixed reducing the rack, pinch roller rack). Composite tungsten carbide roller is made of cemented carbide and other materials, and it can be divided into tungsten carbide composite roll rings and solid tungsten carbide composite roller. Tungsten carbide composite roll rings mounted on the roller shaft; solid tungsten carbide composite roller will be directly cast in the roll axis to form a whole, a large load is applied to the rolling mill. Tungsten carbide roller production process control Tungsten carbide rollers produced by powder metallurgy method, the key to its process control is the chemical composition of the material and the mixture was prepared, pressed molding, sintering and deep processing and other preparation process parameters. 1. Preparation of starting material (WC focus quality): As the WC raw material and quality control of the use of different levels of quality may fluctuate, resulting in adverse effects on microstructure. 2. Preparation of the mixture: Mixture preparation is the key to the production process of the roller, the roller of failure modes - trachoma, mainly generated by this procedure. 3. Pressing: roller pressing is an important process of the roller mill. 4. Sintering: roller sintering is to determine the final quality of the roller production processes, use of advanced low-pressure sintering technology, HIP sintering technology can greatly improve the performance of roller. 5.
